Hello,
I have reinstalled openhabian 3 on a Raspberry Pi 4 Model B Rev 1.2.
before, the Pi was running openhabian 2 without any problems.
The installation also ran without error messages.
I can access via ssh and I have set the PI to a fixed IP.
Everything runs without error messages.
But I can’t access openhabian 3 via the fixed IP and port 8080.
What could be the problem?
Best regards

Which release (stable/unstable) of OH3 did you install?
There was some problem with snapshot build. See here:
OH3 MainUI, Browser shows blank page after login - Add-ons / UIs - openHAB Community
There is no such thing.
It is called openHAB 3.
Is there any error message in /var/log/openhab.log ?
what does
sudo netstat -tulpn
show ?
There is no port in LISTENing mode that belongs to a java process.
There must be a generic problem that it is not running / working.
Try to start openhab manually:
sudo systemctl start openhab
Check the status of the service
sudo systemctl status openhab
What is the output of the status ?
If it is not running but shows an error message like exited or what ever in the upper part of the returned message then please run
sudo journalctl | grep openhab
Please also have a look to the content of the file /var/log/openhab/openhab.log if it explains what went wrong.
I see that you run frontail ( port 9001 ) you may have a look and check if you can see messages about the problem in the browser. In that case you do not need to open the file manually.
Just to check:
java -version
shows that Zulu 11.X is installed ?
Hello,
I have now entered the commands and attached the results as a picture.
Your first picture shows a permission issue for the temp folder. Please use “fix permissions” in openHABian.
Thank you for your help.
That was exactly the problem.
Now I can start Openhab 3.
Best regards
Great, please mark this topic as solved then.
another reason why UI stops working could be that there is a page/chart which does not have a label.
have a look at the file /userdata/jsondb/uicomponents_ui_page.json and verify that all pages have
a label in the section “config” which is within “value”. You can fix it there directly. Take care of permissions and ownerships and the restart OH.
(This problem can happen when you create pages through API and forget to set the label)
Hi all,
I am facing the same problem currently, which means I cannot reach Main UI.
Description of the issue:
The chrome tab is loading and loading but never reaches the UI. Also Andriod App is loading only. myopenhab.org shows OH is offline which is in fact not correct. OH has been started and indeed it’s working - rules are fired (e.g. garden lights went on and off, Broadcast Notifications are sent, …).
I have several tablets showing Habpanel. The tablets with habpanel running (Fully Kiosk browser) are showing it, but no response on any switch for example. But the status is updated but with a big time delay (not sure about the exact time, but in a range of >15mins roughly). Some item’s status is combined with a broadcast notification which is sent just in time, so no delay. One tablet was off when the problem occured (or was recognized), there Fully kiosk browser is loading but habpabel never appears there.
Possible related topics / root-cause (?):
What I already did:
I guess that it’s somehow related to the installation of Dropbox and therefore sort of port issue. To be honest I am not sure about the exact timing of Dropbox installation / binding installations and OH update. Maybe something went wrong during any installation or update process due a port issue while Dropbox was running?
I had several issues in the past, but Main UI was somehow giving a hint because a certain Thing was offline or anything like that. But since I cannot access UI, I have no idea - beside clearing cache and tmp + restart, which did not solve it…
Does anyone have an idea where to look at? I’m lost at the moment…
Edit @ 2021-12-16 / 20:15:
after a few trials (restart, …) I was able to acces Main UI for a few seconds directly after OH startup. Unfortunately the time was too short for any further click…
Due to that fact, I guess something happens after startup (instead of a general problem like ports are blocked). Checking openhab.log brings me to following conspicuousness:

After those ones, there are only entries coming from rules

OH is running (rules, …) no access to Main UI, Habpabel, Android App.
Is this somehow helpful for troubleshooting?
